n NECK-YOKE.

SPECIFICATION forming part of kllietters 'Patent No. 269,858, dated January 2, 18.83.

(No model.)

To all whom it may concern:

Be it known that I, JAMES HoLL1srEa,a resident of St. Paul, in the county of Ramsey and State ot' Minnesota, have invented certain new and useful Improvements in Three-Horse Neck-Yoke Eveners, ot' which the following is a specification. K

This invention relates to three-horse neckyoke eveners, and it consists in the construction andarrangementofpartshereinaftershown and described, and sought to be specifically claimed.

Figure 1 is a rear view, and Fig.- 2 is an end view, of the yoke or evener and a portion of the forward end of the wagon-tongue, showing their relative positions. Fig. Sisa perspective view ot' the evener, and diagrams oi' portions of the harness of the three horses, illustrating the manner of connecting them.

This device is intended to be used only when three horses are driven abreast to equalize the strain when backing or turning short angles, and consists in a main part or single-tree, A, having an eye or ring, a., by which the tongue B is held thereon, and two whiffletrees, G D, connected to the ends ofthe single-tree byl flexible couplings b, as shown. The ring or eye a is not in the'center of the single-tree A, as Will be seen, but is at a point about one-half the distance between one-third and one-half the llength of the single-tree, or about ivetwelfths the length ofthe single-tree from one end and seven-twelfths the length ot' the single-tree from the other end, thus leaving one end two-twelt'ths'longer than the other end. Two ofthe horses will be placed upon the side of the tongue next the long end ot' the singletree and one of the horses on the side next the. short end.

The whidetree C is about live-sixths the length of the single-tree, and the whiftletree D is about two-thirds the length of the whiftletree C. The whiffletrees C I) are pivoted at b to the ends ot' the single-tree A in the ordinary manner by flexible rings or eyes, and provided on their ends with rings or eyes e, by which the'horses are attached. The pivotb ot' the whietree U is placed about one-third its length from one end, with the short end outward and the long end inward toward and extendingl beyond the tongue B a short distance,

while the pivot b of the whiftletree D .is placed about one-fourth the length of the Whiflletree from the outer end, and with the long end inward toward and nearly to the inner end ot' the whiftletree (j.

In Fig. 3 is shown the evener on a smaller scalein perspective,and also the haines EEZE, and breechingportionsF F2 Fof the harnesses of the three horses in their relative positions.

The haines and breeching of the outside horses are connected by straps, as indicated by dotted lines gli, in the ordinary manner, to the short outer ends ot' the Whifdetrees C D, while the hames and breeching of the central horse are similarly attached, as indicated by dotted lines t' k, to the inwardly-extending long ends of both the whifdetrees U D. By this a1'- rangeinent the central horse, in backing, draws upon both the whiiiletrees C and D by their long` ends, and the outer lhorses each draw backward upon one of the same whiflletrees, and by the position of the pivoted points ot' whiffletrees U l), and also of the single-tree A upon the tongueB, the leverage is so equalized that allv three of the horses are subjected to the same strain, and all bearau equal share of the work in backing or turning.

Ordinarily, where three horses are used, the Work ot' backing or turning comes entirely upon the two horses immediately' next the tongue, the third horse having no share in it; b ut by this arrangement the work is evenly divided among them all.

This device is especially adapted to harvesting machinery, but may be used Wherever three horses are driven abreast. Where all the horses are of about the saine weight and strength the pivotal points will beplaced at aboutthe points shown; but by providing a number of holes, m, for the pivotsb ot' the whiftletrees the leverage of the whiftletrees may be altered to adapt the device to a lighter or heavier horse to give such animal the benefit of the additional or decreased leverage.

Having described in vinvention and set forth its merits, what I claim is- 1. A three-horse equahziug neck-yoke co nsistingofthesingle-treeA, provided with means forpivotingittoatongue,B,incolnbinatioiuvith whifetrees C and D, provided with means i'or attachment to harness, and pivoted to said sin.
